IMPROVEMENT IN CHANDELIERS.

Specification forming part of Letters Patent No. 147,164, dated February Il, 1874; application tiled l September 17, 1872.

lone common point, and in which the gas may be admitted independently to each separate set, as is the case in some chandeliers and gasrings provided with double-cone reflectors for illuminating churches and other public edices.

The object of the invention is to enable the distribution of gas to each set separately, in such Y a manner as not to obstruct the reiection of light by stop-cocks with their operating attachments heretofore used on the radial pipes of the gas-rings underneath the reilector, and yet to maintain the facility of attachment and neatness of appearance eil'ected by the usual application of only one supply-pipe in the center of the double-cone reflector.

The manner in which I accomplish this is clearly shown in the accompanying drawing, in which- Figure l represents, in section, a portion of the ceiling of a church or other building and a reector of my manufacture inserted therein, and combined therewith a side view of an apparatus embodying my presentinvention. Fig. 2 is an enlarged side view of the said apparatus, partly in section.

Similar letters of reference indicate like parts.

Ais the ceiling, into which is inserted or from which suspended the reflector B. C is a larger, and D a smaller, gas-ring or set of burners. E is the pipe for supplying gas to the upper set of burners C, by opening the cocl; a. The pipe E is placed in or above the ceiling, as usual, and from thence passes down through the retlector. The ring C is attached to a gas-chamber, F, screwed onto the lower end ci' the pipe E. G is a feeler or a small pipe, constantly supplied with gas, and leading to both gasrin gs, maintaining very small llames b c, merely for lighting the gas in the rings C D instantly on its being admitted. On opening the cock a', gas is admitted in the direction oi' the arrows 1, through the pipe E and chamber F, into the ring (or set of burners) C, without admitting' any gas to the other ring D.

To admit gas to the ring or set of burners I) independently of the ring O, I attach, by a joint, H, to the pipe E, another and smaller vide the said pipe I with a cock, d. I then run the pipe I into the pipe E, where the same runs perpendicularly, securing the two pipes together by the double joint J Ithen continue the pipe I through the center or inside of the pipe E down to and through the chamber F, threading the lower end of the pipe I a sufficient distance to allow of its being screwed into the lower part of the chamber F, and protrudin g below the same far enough for attach ing. the lower gas-ring D. On opening the cock d', the gas will thus pass in the direction of the arrows 2 from the pipe E through the pipe I to the lower set of burners D independently of its admittance to the ring C. Thus the two sets of burners O and D may be used separately; or, by opening both cocks a and d', they may be used at the same time. The insertion of the pipe I inside the pipe E maintains, also, the same neatness of appearance and facility for attaching the reilector B, chamber F, and rings G and D as though the pipe E alone were used. The cocks a d are closed simply by the gravity of their weighted handles, and opened by cords and bell-cranks attached thereto in the ordinary manner, as shown in the drawing.

The feeler Gr I attach-to the pipe I at a point anterior to the entering of the gas to the stopcocl; d', in order to always maintain the usual ame for ignitin g the gas in the rings or chandeliers.

By the arrangement of the pipe I branching oli` from the pipe E above the reiiector, then provided with the stop-cock d', and then reentering the vertical portion of the pipe E and continuing through the inside of the same and through the gas-chamber F, then secured gastight in the lower end of and protruding a distance below the said chamber for the attach pipe, I, branching oft' from the pipe E, and pro- I claim as new, and desire to secure by Letters Patent, is

The arrangement of the pipes I and E, in connection with eaeh other and with the cooks a d', chamber F, separate sets of burners C l), and a reiieotor, B, in the manner and for the purpose substantially as shown and described.
